WiFi not connecting in Ubuntu 14.04 (Dual boot)

Question

My Sys Spec: HP-Laptop (Pavilion Notebook) Os : Window 10(Original with Laptop) , Ubuntu-14.04 (Dual Boot)

My system has dual boot, Windows-10 and Ubuntu-14.04. After installing ubuntu, I am unable to see Wifi Connections and unable to connect to Wifi (Wireless) Connections. However I am able to connect through Wired (LAN) Connections

This issue is not there in Window-10. Its working fine in Windows-10.

Can anyone help me on this please ?

Add these lines by running sudo nano /etc/network/interfaces

auto wlan0 >iface wlan0 inet dhcp — EODCraft Staff, May 08 '17 at 10:07

Run this command on terminal:

cat /etc/network/interfaces

If you are getting:

interfaces(5) file used by ifup(8) and ifdown(8) auto lo iface lo inet loopback

Your problem is sorted ,you have to just add two lines: Run on terminal :

sudo nano /etc/network/interfaces

Then add these two lines at the end

auto wlan0 
iface wlan0 inet dhcp

Ctrl+x Then type y to say yes for saving the file and then press enter
Restart your system.
